This work examines the process of software development from Informing Sciences (IS) point of view. We explore how the three IS precursor theories--Shannon and Weaver’s Model of the communication process, Leavitt’s Change-equilibrium model, and the “Meta-approach” to mod-eling--justify a model-driven approach to software development and we argue that modeling through abstraction, metaphoric mapping and metaphoric comparison is the link holding together the three cornerstone theories of IS.
